Abstract (en)
A fiber optic array has a plurality of subarrays (SA1, SA2) of optical sensors, the subarrays being spaced apart along and optically connected to input and output buses (14, 16) through associated input and output optically actuated optical switches (S11, S12) in series in the input and output buses. First and second light signal pulse trains (P, 5) are applied to one and other ends of the input bus (14) and a third light signal pulse train (Q) is applied to one end of the output bus (16). The input switches (S11, S12) are sequentially responsive to each first light signal pulse (P) on the input bus (14) for passing to an associated subarray a pulse of second light signal (S) that is simultaneously present at that input switch such that second light signal pulses of the same magnitude are applied to each subarray. Associated output switches (S21, S22) are sequentially responsive to third light signal pulses (Q) for passing trains of second light signal pulses from the arrays onto the output bus (16) and to processing equipment (34). <IMAGE>
